Abstract: A straddle type vehicle with its fuel tank covered with a tank cover, in which misalignment between a filler opening on an upper part of the fuel tank and an orifice for exposing the filler opening out of the tank cover is restrained. The tank cover includes a center cover on which the orifice is formed, and right and left side covers molded separately from the center cover and disposed on right and left sides of the center cover for covering the fuel tank from the side.

Abstract: A motorcycle having a meter device and a handlebar cover arranged to inhibit damage or the adherence of powder coating to the meter device from the handlebar cover. In one embodiment, a rear cover comprises a peripheral wall, which surrounds an outer periphery of a meter device. At least a front portion of the peripheral wall, which surrounds a front side of the meter device, comprises a first portion and a second portion. The first portion is positioned inside the front cover. An outer surface of the second portion is exposed between a rear edge of the front cover and the meter. A dimension of the first portion and the second portion are the same in a longitudinal direction of the motorcycle, or the second portion is smaller than the first portion.

Abstract: A motorcycle with increased freedom in selection of a location in which a passenger puts a foot has a footboard, a seat and a side cover. The footboard includes footboard extensions extending rearwardly of a foremost portion of the seat toward the rear. The footboard extensions include a projection projecting outward of a vehicle body beyond a portion of the side cover positioned outermost in a vehicle width direction. Folding type footrests for a passenger are below the projections.

Abstract: A deodorant, for substances containing hydrogen sulfide or mercaptans, which includes a combination of a peroxide and a nitrate ion, a combination of a peroxide, a nitrate ion and a metal salt, or a combination of a chelating agent and one of the above combinations, and a process for deodorization comprising treating a substance for treatment, containing hydrogen sulfide or mercaptans, with the above deodorant. Smell caused by hydrogen sulfide or mercaptans is effectively removed by the deodorant. Smell from waste water, sludge, and water discharged from washing apparatuses can be efficiently removed with use of the deodorant in a small amount in accordance with this process.

Abstract: Emission of NOx during acid-piclding treatment of metals in an aqueous solution containing at least nitric acid is controlled by the addition of hydrogen peroxide. The addition amount of hydrogen peroxide is minimized to avoid excessive addition by monitoring the potentiostatic electrolytic current of the solution or by combinedly monitoring the potentiostatic electrolytic current and the redox potential of the solution.

Abstract: A chemically and physically stable humidity sensor including a porous sintered body and electrodes, which is formed by bringing a humidity sensor including a porous sintered body and electrodes into contact with a solution of a polyurethane resin.

Abstract: A humidity-sensing component composition includes a metallic oxide and a chalcogen oxyacid salt represented by a general formula A.sub.x B.sub.y O.sub.z where A is one of an alkali metal and an alkaline earth metal, B is one of sulphur, selenium, and tellurium, O is oxygen, x is 1 to 2, y 1 to 5, and z 2 to 7. The chalcogen oxyacid salt is blended by an amount of 0.01 to 99.99 mol % in the metallic oxide with the sum of the metallic oxide and the chalcogen oxyacid salt as a reference. The metallic oxide and the chalcogen oxyacid salt are sintered under an atmosphere of molecular oxygen.

Abstract: A protective cover for photoprinting system comprises a cover portion made of a transparent thin plate of inorganic material, an antireflection multiple coating provided on at least one of the inner and outer surfaces of the cover plate, and a spacer arranged on the peripheral portion of the cover plate for keeping the inner surface of the cover plate away from the surface to be protected, e.g., pattern surface of photomask and sealing the space between them.Since the cover plate is made of inorganic material, the mechanical strength thereof is large. Since the cover plate is thin and the antireflection multiple coating is provided on the cover plate, absorption of light therein is little and confusion of the pattern image due to rays reflected by the boundaries of the cover plate is ignorable.
